How to change the pixel shader to achieve the purpose of changing the color of the character。
I have read the directx 12 book, but I cannot get the target-PipelineState.
How to rewrite the state of the deep template to achieve wallhook.
I only get PipelineState through HOOK-SetPipelineState, and ID3DBlob through GetCachedBlob. ID3DBlob will not be converted to D3D12_GRAPHICS_PIPELINE_STATE_DESC.
